Title: Color identifying device
Inventor: SHIMIZU MASAO
IPC: H04N7/18
Filed: 1990-03-19
Abstract: PURPOSE:To color-identify the feature representation of input picture information automatically and at high speed by transferring an n-dimensional feature vector into an m-dimensional finding a histogram and moreover, classifying by the technique of a main component analysis. CONSTITUTION:An n-dimensional feature vector constituting circuit 41 executes statistic processing after converting picture signals R, G and B into the color difference signals of R-Y and B-Y and a Y signal. An n-dimension   m- dimension mapping circuit 44 maps in m-dimensional feature space with a main component analysis technique based on a respective axis histogram and covariance matrix on an n-dimensional vector generated by a respective axis histogram generating circuit 42 and a covariance matrix generating circuit 43. Next, respective axis histogram generating circuits 451 to 45m generate the respective dimensional histograms of a m-dimensional feature vector. m Comparators 461 to 46m set threshold values on the m-dimension at every respec tive axis and classify. An encoder 47 puts classified colors together moreover and input picture information can be color-identified automatically and at high speed so that a feature may be represented most effectively.

Title: Heat-developable photosensitive material
Inventor: HIRAI HIROYUKI
IPC: G03C8/40
Filed: 1983-04-20
Abstract: PURPOSE:To improve the shelf stability before heat development and to form a high-density image with little fog by incorporating an alkali metallic or alkaline earth metallic salt of carboxylic acid as a base precursor. CONSTITUTION:An alkali metallic or alkaline earth metallic salt of carboxylic acid is incorporated into a heat-developable photosensitive material as a base precursor. The preferred base precursor produces a base by decarbonation at about 80-250 deg.C, and CCl3CO2Na, ClC6H4SO2CH2CO2Na or the like is used as the precursor. The precursor is chemically concerned with silver halide during heating and accelerates development. The precursor may be present at any position of the photosensitive material, yet it is preferable that the precursor is not contained in each silver halide emulsion layer or its adjacent layers. The precursor is very effective in an image forming method by which a movable dye is formed by heating and transferred to a dye fixing layer. When a photosensitive layer and a dye fixing layer are formed on separate supports, the base precursor is incorporated into the fixing layer.

IPC: F04D9/02
Filed: 1989-03-22
Abstract: PURPOSE:To prevent the fixing of a fixed sealing member and a movable sealing member with sliding surfaces thereof by forming a passage for communicating a delivery tank with sealing members. CONSTITUTION:An impeller is housed in an impeller chamber 2 in an impeller casing 1 and fixed in a rotary shaft 22, and both ends of a pipe 10 are connected to through channels 11 and 12 to form a passage which can communicate the delivery tank 4 with sealing members.

In this case, a ring space 16 pinched by a bottom plate 15 and a wall plate 14 is formed in the periphery of the sliding part of a fixed sealing member 36 and a movable sealing member 37 by providing the wall plate 14, and the water flowed from the delivery tank 4 fills the space 16. The outflow is restricted by the wall plate 14 even if the inflow from the tank 4 is very a little, and the sliding part of both sealing members 36, 37 is filled with the sufficient water.

Abstract: PROBLEM TO BE SOLVED: To prevent thermal harm such as thermal death in a vehicle by oscillating a high frequency signal including frequency scanning means, transmitting it to a sensor including a resonance circuit, detecting a signal according to the external condition of the sensor, judging the existence of a human body from the detected signal and an oscillated frequency, and controlling an air conditioner in an interior. SOLUTION: In a human body sensor 1, a high frequency signal is generated in an oscillator 13 and supplied to a sensor 11 through a transmission pass 14, and the high frequency signal of an oscillator 12 is scanned in a range of from 30MHz to 50MHz. The high frequency signal supplied to the sensor 11 is reflected, and the magnetic permeability and displacement current of a body differ from each other according to the body placed in the vicinity of a detecting coil 21 in the sensor 11, therefore the impedances of the sensor 11 differ from each other, and the vicinity of the coil 21, that is, the levels of a reflected wave generated by an external condition differ from each other.  This reflected wave is detected by a reflected wave sensor 13, and vacancy, cargos, human bodies, and so on are judged and detected from the reflected wave level and the frequency in a controller 15, and temperature is controlled by an interior temperature controlling part 2.

IPC: B23K26/382
Filed: 1993-03-29
Abstract: PURPOSE:To allow only the conductive layer to remain with high accuracy by forming a groove, hole, etc., in a laminated substrate and irradiating this part with a laser beam to remove a desired layer. CONSTITUTION:The lancing groove or hole of a required processing width is formed on the insulating layer 1 of the laminated substrate, for example, circuit board 3. The processed circuit board 3 is placed on a table 10. The insulating layer 1 remaining in the groove formed on the circuit board 3 is irradiated with the laser beam outputted from a pulse laser oscillator 11. The reflected laser beam is received by a photodetector 15. This pulse laser oscillator 11 receives the detected light quantity signal from the photodetector 15 and stops the oscillation of pulse lasers on judging that the received light quantity attains the detected light quantity from copper foil 2. The circuit board 3 is so processed that only the insulating layer 1 remaining in the groove bottom of the circuit board is removed and that only the copper foil 2 remains.

Abstract: PURPOSE:To suppress an influence due to deviation of a detecting position of an alignment mark caused by the orientation of film growth by flattening the surface, on the bottom part of a recessed part, of a film constituting a semiconductor element at a specific position of a wafer substrate. CONSTITUTION:The bottom face 2a of a film 2 formed on a substrate 1 provided with an alignment mark by means of a level difference 1a is generally swelled.
